Hi Rick, The difference is called propagation, and you have the advantage of being in line-of-sight. Even a Christmas tree bulb can communicate that far at those antenna heights. 73's Richard Clark, KB7QHC |

Hi Rick, The difference is called propagation, and you have the advantage of being in line-of-sight. Even a Christmas tree bulb can communicate that far at those antenna heights. Good afternoon, Richard. I guess I wasn't clear. Stations A (me) and B are 10 miles apart. Station C is 90 miles from both stations A and B, broadside to a line between stations A and B. Station A runs a cut dipole at 17 feet and Station B runs a B&W at 25 feet. Station C comes in weak at Station B (with the B&W) but strong at Station A (with the cut dipole). I suppose that propagation between Stations C and A will be different than between C and B, but usually not that different... |

I suppose that propagation between Stations C and A will be different than between C and B, but usually not that different... It would be a curious exception, indeed. I can imagine the difference in A/B received signal strengths is found in the tuner at A. 73's Richard Clark, KB7QHC |
